SPECIFICATION forming' part 0f Letters Patent N0. 680,778, dated August20, 1901. Application filed May 14, 1901. Serial No. 60,233. (No model.)

To all whom t may concern,.-

Be it known that I, OSCAR JANELLE, a citizen of the United States,residing at Manchester, county of Hillsboro, State of New Hampshire,have invented an Improvement in Looms, of which the followingdescription, in connection with the accompanying drawings, is aspecification, like characters on the drawings representing like parts.

1o This invention has for its object the production of novel means forpreventing rebound of the shuttle when it enters the shuttlc-box of aloom.

Various novel features of my invention will be hereinafter described,and particularly pointed out in the following claims.

AFigure lis atop or plan View, partly broken ont, of the left-hand endof the lay of a loom with one embodiment of my invention ap- 2o pliedthereto. Eig. 2 is a rear elevation of the parts shown in Fig. l; andFig. 3 is a right-hand end elevation of the lay and adjacent parts shownin Fig. 2, with a part of the picker-check broken out.

I have herein shown the lay A3 as having a shuttle-box thereoncomprising a front plate or wall B, back wall B', overhangngshuttleguard B2, and a binder BX, pivotally mounted near the outer endof the lay at hX, which may 3o be all of usual or well-knownconstruction, the lay being longitudinally slotted at AX for the staffof the usual picker P. A suitable binder-spring S bears against the backof the binder and is secured to the lay at 3, and the ,35 protectorrock-shaft p, mounted in bearings ,79X beneath the lay, the dagger p',rocker-arm p2, having the upturned finger p3 to bear against the freeend of the binder, and the 4controlling-spring SX are also of usual con-4o struction and operate in a Wellknown manner.

The impact of the shuttle upon the swell of the binder at the high :rateof speed of the shuttle as it enters the shuttle-box throws the binderout against the spring S and the spring SX of the protector mechanism,and before the binder can return to engage and prevent Jthe shuttle fromrebounding the shuttle hits the picker and tends to bound back.

5o I have herein provided means to accelerate the return of the binderto properly check rebound of the shuttle, such means being madeoperative by or through the impact of the entering shnttle upon thepicker.

A bracket o, secured to the lay, has bearings aX for a short rock-shafta', having secured to it an upturned arm d2, provided with an eye a3,through which is extended a pusher, shown as a short rod d4, held inadjusted position by a set-screw 4., the front end 6o of the pusherbeing behind and normally out of engagement with the binder. A spring S'surrounds the shaft a between its bearings, one end of the spring beingfixed to one of the bearings and the other end to a collar 5, fast onthe shaft, the spring normally maintaining the parts in the positionshown, a stop G on the collar engaging the lay (see Fig.

3) and limiting the rotation of the shaft a. in the direction of arrow8. The outer end of 7o the shaft has secured thereto, preferablyadjustably, by a set-screw l0 a hub co5, having a depending leg a6,Which'at its lower end is laterally enlarged to form a foot a7,extending parallel to and normally partly in the path of thepicker-staff PX and beveled or dared at its inner end. (See Fig. 2.) TheVertical face of the foot is preferably covered With leather or othersuitable cushioning material, as 20, and the covered foot constitutes 8oa movable buffer forming one member of a picker-check, the latter alsoincluding a fixed buffer located opposite to the movable buffer andherein shown as a suitably-shaped head ctw on the lower end of a bracketC013, secured to the lay, said head being also covered with cushioningmateriaLsuch as leather or thelike 22,and the fixed buffer is alsobeveled or flared at its inner end, the straight vertical face of thebuffer being shown as substantially 9o coincident with one side of thepath of the picker-staff, the flared inner ends of the two buffers,which normally are in the position shown in the drawings andparticularly referring to Figs. l and 3, constituting a Wide entrancefor the picker-staff on its outward stroke. When the shuttle enters theshuttleboX, it hits the swell of the binder BX and throws the latteroutward with great violence, suchmovementofthebinderbeingopposedby roothe action of the springs S SX, and the shuttle as it continues itsmovement toward the end of the lay hits the picker and the latter ismoved with the shuttle. Such impact of the shuttle upon the pickerdrives the picker-staff* between the fixed and movable bufferscomprising the picker-check and presses the movable buffer a7 toward theback of the loom to thereby rock the shaft a' in the opposite directionto the arrow 8, and such rocking of the shaft moves the pusher a4forward to engage and push the binder back toward the front of theshuttle-box, accelerating its return by the quick sharp blow i mpartedto it by the pusher.

The separation of the buiers against the action of the spring S'operates at the same time as a check for the picker, and theacceleration imparted to the binder on its return movement brings thebinder into position to engage the side of the shuttle before the latterhas had an opportunity to rebound, such engagement of the binder withthe shuttle thereby checking and preventing rebound of the shuttle.

When the picker is thrown inward by any usual actuating means, (notshown,) lthe picker-staff passes out from between the fixed and movablebuffers constituting the pickercheck, and the movable buffer returns tonormal position, (shown in Fig. 1,) and at the same time the pusher a4is withdrawn from engagement with the binder, so that the latter is leftentirely to the control of the hinder-spring and the spring on theprotector rock-shaft at the next impact of the entering shuttle.

By the construction herein shown the resistance of the binder and theimpact of the shuttle are not increased, but an additional impulse isgiven to assist the return of the binder to operative position intime toengage and prevent rebound of the shuttle.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. In a loom, the lay, a shuttle-box thereon, a spring-controlled binderthrown out by impact of the entering shuttle, the picker, a picker-checkcomprising a fixed and a yielding buffer, between which the pickerpasses when struck by the entering shuttle, and

means actuated by movement of the yielding buer to engage and acceleratethe return of the binder to position to prevent rebound of the shuttle.

2. In a loom, the lay, a shuttle-box thereon, a binder, the picker, aspring-controlled rockshaft on the lay and having a inger to coperatewith and resist outward movement of the binder, a second rock-shaft alsomounted on the lay and having an arm to coperate with the binder, andmeans operated by shuttle-induced movement of the picker to rock thesecond rock-shaft and bring the arm thereof into engagement with thebinder, to accelerate the return of the latter to position to cooperatewith the shuttle.

3. In a loom, the lay, a shuttle-box thereon, a binder, the picker, apicker-check having a buffer movable by engagement with the picker, apivotally-mounted arm on the lay and normally inoperative, andconnections between the buer and arm to move the latter toward and toengage the binder to accelerate its inward movement into checking.position for the shuttle.
